Frequently Asked Questions

We know, right? It’s partly because of the clever construction, partly because of the first-rate fabric blend, and partly because it supports your body without feeling constricting.

They're both! We’re glad you asked. Think of them as a combination between an old-school slip, a boxer brief and biker shorts: They give you coverage under short or too-sheer outfits, stop your inner thighs from trying to start a forest fire, and light smoothing with no VPL (the word “panties” weirds us out, too). Plus, the knit-in cotton-rich crotch means you can wear them without underwear if you want, eliminating the need for an extra layer.

Thigh Society shorts don’t compress you or suck you in like shapewear. Instead, they’re a lightweight, breathable, sweat-wicking essential you’ll reach for again and again.

Flexible and stretchy, our waistband is made from the same fabric as the shorts, just double-folded and sewn-in. It stretches to your curves, never cuts into them. The waistband is like the Loch Ness Monster: you’ll doubt it really exists.

Super comfortable

These under shorts are the best I have ever tried. Cool, comfortable and smoothing. I have tried other brands and they always roll up in the high waist area. These did not. I bought a lighter color too

Comfortable and stay in place!

These work really well. They’re soft, comfortable and breathable, and they stay in place without rolling up. Easy to wear under most dresses and, most importantly, no chafing. A simple, comfortable solution that does exactly what I wanted. Purchased in beige AND black.

Bought for wearing under skirts, which they're great for, and now I basically live in them as lounge wear. It's true to size, but since I'm XL+ I should've gotten a size up. Still great! Just learn from my mistake ♥️
